        Examining English Test Practicality among Different Stakeholders in Thailand

        Arnon Chaisuriya,신선영 아시아테플 2019 The Journal of Asia TEFL Vol.16 No.1

        This study investigated perceptions of university students from various areas in Thailand regarding aspects of English test practicality including affordability, convenience, resources, contents, and delivery modes. 210 students filled out a questionnaire consisting of three sections: demographic data, perceptions of test practicality, and views on content and delivery. The data was further analyzed to see whether any differences in the perceptions of test practicality existed between students from universities in Bangkok and those from other regional universities. An additional analysis was conducted to examine relationship between their perceptions and other variables, such as socio-economic status (SES) and gender. The results revealed that Thai university students viewed the test of English for international communication as important for their future careers despite their unfamiliarity with it. Several aspects of practicality can be enhanced by taking extra steps, such as organizing orientations for high-school students or college freshmen, offering scholarships and fee waivers, and creating a level-based test. Stakeholders from middle-income families and those outside the metropolis had acquaintance with and an encouraging attitude toward the test and the opportunity to achieve a higher score. Regarding gender’s effects on test practicality, while male students embraced computer and the Internet as the new delivery mode, female students, on the other hand, seemed reluctant to do so.

        SCHATTEN'S THEOREM ON ABSOLUTE SCHUR ALGEBRAS

        Rakbud, Jitti,Chaisuriya, Pachara Korean Mathematical Society 2008 대한수학회지 Vol.45 No.2

        In this paper, we study duality in the absolute Schur algebras that were first introduced in [1] and extended in [5]. This is done in a way analogous to the classical Schatten's Theorem on the Banach space $B(l_2)$ of bounded linear operators on $l_2$ involving the duality relation among the class of compact operators K, the trace class $C_1$ and $B(l_2)$. We also study the reflexivity in such the algebras.

        SCHATTEN CLASSES OF MATRICES IN A GENERALIZED B(l<sub>2</sub>)

        Rakbud, Jitti,Chaisuriya, Pachara Korean Mathematical Society 2010 대한수학회지 Vol.47 No.1

        In this paper, we study a generalization of the Banach space B($l_2$) of all bounded linear operators on $l_2$. Over this space, we present some reasonable ways to define Schatten-type classes which are generalizations of the classical Schatten classes of compact operators on $l_2$.
